Description
Technical field:
The utility model relates to a kind of baggage elevator, companion ladder and locatees anti-fall device in the air, belongs to elevator ensuring equipment manufacturing field is installed.
Background technology:
Existing baggage elevator, companion ladder do not have falling proof device on structure design, control its skyborne stop with the brake gear in its drive controlling mechanism entirely.Its weak point is: the one, owing to baggage elevator, companion ladder mainly convey goods, its weight is big, particularly when parcel move into, take out of or advance, when releasing freight lift or companion ladder, must produce an impulsive contact force to freight lift or elevator, directly affact the brake gear in the drive controlling mechanism, if things go on like this directly have influence on the reliability of brake gear; The 2nd, because baggage elevator, companion ladder be not owing to there is falling proof device, in case the traction steel wire fracture of rope takes place, its consequence is unimaginable.
Summary of the invention:
Design goal: avoid the weak point in the background technology, design a kind of falling proof device that baggage elevator, companion ladder can be located stop aloft.
Design plan: in order to realize above-mentioned design goal.1, at baggage elevator, falling proof device is set on the companion ladder, it is one of feature of the present utility model, this falling proof device is the retention period aloft, enough brake weights that brake gear in the drive controlling mechanism is born are born by falling proof device, that is to say, baggage elevator, when companion ladder stops handling goods aloft, support baggage elevator, the power of companion ladder is not the brake gear that comes from the drive controlling mechanism, but from falling proof device, parcel is moved into, take out of or advance, when releasing freight lift or companion ladder, to the impulsive contact force that freight lift or elevator produced is not the brake gear that acts directly in the drive controlling mechanism, but act directly on the falling proof device, not only can avoid the weak point in the background technology effectively, and played the function of double insurance, guaranteed baggage elevator, the safe in operation of companion ladder.2, the design of fork bar linkage structure is two of a feature of the present utility model, and to the stirring of fork head, connecting rod mechanism opposite or relative motion in the fork band left and right sides can realize stretching out and indentation of left and right sides axostylus axostyle by the dead man head.Two axostylus axostyles stretch out the knock hole that enters (being arranged on track or support or the wallboard) stay bearing plate, can be by frame aloft with baggage elevator, companion ladder case two ends, brake gear in the drive controlling mechanism is not carried in the process of cargo handing, avoided parcel move into, take out of or advance, when releasing freight lift or companion ladder, brake gear in the drive controlling mechanism is collided, guaranteed the safety of operation.3, the bar portion of dead man is connected with baggage elevator, elevator door and the head that pulls out of dead man is used to stir the structure design of fork, it is three of feature of the present utility model, the maximum characteristics of this structure are: guaranteed the synchronized operation of fork connecting rod mechanism and baggage elevator, elevator door, realized the door open, baggage elevator, companion ladder case two ends are by frame aloft, rather than be hung in the air, both made this moment haulage cable disconnected, can not fall yet; Door closes, the axle indentation automatically of stretching out in the fork connecting rod mechanism, and baggage elevator, companion ladder be operation up and down normally.
Technical scheme: baggage elevator companion ladder falling proof device, connecting rod III (4) two ends are hinged with bracket I (6) and bracket I I (7) respectively, one end of two bull sticks (5) is affixed with connecting rod III (4) respectively, an end of the other end and connecting rod I (2) and connecting rod (3) is hinged, the other end of connecting rod I (2) and connecting rod (3) is hinged with an end of axle (9) respectively, the other end of diaxon (9) debouches the supported hole (10) in the stay bearing plate (8) respectively, and the head that pulls out of fork (1) and dead man (11) affixed with connecting rod III (4) matches with the jaw of fork (1).The method of its fall arrest: when baggage elevator door or elevator door are opened, the dead man (11) that is positioned on baggage elevator door or the elevator door moves with door, the head that pulls out of dead man is stirred a fork arm of fork (1) and is forced this fork arm drivening rod III (4) to rotate, connecting rod III drives two bull sticks (5) to two lateral movements, two bull stick drivening rod I (2) and connecting rod II (3) be to two lateral movements, and connecting rod I (2) and connecting rod II (3) drive diaxon (9) and stretch out and lay respectively in the supported hole of stay bearing plate (8) and baggage elevator or companion ladder supported to both sides respectively and locate; When baggage elevator door or elevator door are closed, the dead man (11) that is positioned on baggage elevator door or the elevator door moves with door, the head that pulls out of dead man is stirred another fork arm of fork (1) and is forced another fork arm drivening rod III (4) to rotate, connecting rod III drives two bull sticks (5) relative motion, two bull stick drivening rod I (2) and connecting rod II (3) are to relative motion, and connecting rod I (2) drives axle (9) indentation of the supported hole that is arranged in stay bearing plate (8) with connecting rod II (3) and separates with the supported hole of stay bearing plate.
The utility model is compared with background technology, the one, fundamentally changed baggage elevator, the aerial locate mode of elevator, avoided goods move into, take out of or advance, when releasing, collision to brake gear in baggage elevator, the elevator drives control mechanism, guaranteed the safety of its operation, realize baggage elevator, the aerial double insurance of locating of elevator, fundamentally avoided the baggage elevator of background technology existence, the situation of elevator falls; The 2nd, the design of synchronous automatic control fork double link safety dropping prevent mechanism, not only novel structure, uniqueness, simple, practicality, safe and reliable, and with low cost, operability is extremely strong, in case aerial location, both made haulage cable disconnected, can not obtain beyond thought economic benefit and social benefit in the air yet, really solve the difficult problem of baggage elevator, companion ladder fall arrest from falling.
